VitaBright
5% OffFree Shipping
Why we love it
  • Promotes quality sleep and energy.
  • Fast absorption due to chelation.
  • Strengthens muscle and heart health.
Main Highlights
  • HIGH STRENGTH VEGAN MAGNESIUM GLYCINATE - The recommended 300mg elemental magnesium per day (from 1500mg magnesium) makes these ideal strength magnesium tablets for women and men. Our capsules are vegan and vegetarian.
  • HOW TO USE VITABRIGHT MAGNESIUM GLYCINATE CAPSULES - Take 2 capsules a day with water. We suggest you take magnesium glycinate around 2 hours before you go to sleep. an amino acid that naturally occurs in foods.
  • WANT A MAGNESIUM GLYCINATE DRINK? Simply twist open your VitaBright magnesium capsules and tip the magnesium glycinate powder into fruit juice or, if you prefer, a mug of bedtime milk or cocoa before you go to sleep. This gives you a convenient magnesium glycinate liquid that's more economical than magnesium sachets.
  • CHELATED MAGNESIUM GLYCINATE FOR BETTER ABSORPTION - You want your magnesium tablets high-strength, but remember that high-absorption is equally important - otherwise it will just make you go to the toilet more often. VitaBright’s Magnesium Glycinate is chelated to the amino acid Glycine, forming a molecule of magnesium glycinate/bisglycinate. This means you absorb more, without the tummy trouble.
  • BRITISH MADE QUALITY - We have all our ingredients independently lab tested to guarantee their purity. VitaBright Magnesium Glycinate supplements contain no synthetic binders, no additives, no fillers, no preservatives, no bulking agents, no flow agents. We make our magnesium capsules here in the UK in pharmaceutical grade facilities, working to exacting GMP manufacturing quality standards. We're a British company and we are proud to have millions of loyal customers worldwide.

Why we love it
  • Without the specific product details, I'm afraid I cannot provide the reasons for loving it. Could you please provide some?
Main Highlights
  • FOOD-GROWN MAGNESIUM — Grown in a raw, live food paste. The natural biochemistry is represented along with the glycoproteins, lipids and amino acids. The full spectrum of the seven naturally occurring Magnesium compounds are in this Food-Grown formula. Magnesium tablets as nature intended.
  • OPTIMIZING REST & ENERGY — Magnesium supplements keep hundreds of processes ticking over in the body, including supporting the reduction of tiredness and fatigue. Scientifically-studied Food-Grown Magnesium for sleep is shown to aid with a more restful and deeper night’s sleep. Magnesium’s energy yielding ability also helps support energy levels throughout the day.
  • SUPPORTING BOTH MIND & BODY — Magnesium is a highly versatile nutrient, supporting the normal function of the nervous system and psychological health. Magnesium capsules help the body absorb calcium, strengthen bones and teeth, and are great for muscle recovery and joint stiffness.
  • WHY FOOD-GROWN SUPPLEMENTS? Your DNA is wired to receive nutrition from food, which is exactly why Food-Grown ingredients are kept as close to their original food form as possible. No added fillers or binders, just clean, ethically sourced ingredients, evidenced by research and real life. Five gold-standard scientific absorption studies show just how effectively Food-Grown supplements are absorbed and retained. Let your body decide.
  • WHY WILD NUTRITION? In 2013, with over a decade’s experience running health clinics, nutritional therapist Henrietta Norton felt the supplement industry could do better. And so, Wild Nutrition was born. Fast forward to today and Henrietta’s Food-Grown formulations are loved across the globe. Certified B Corp in 2021, Pioneers in Food-Grown supplements.

Why we love it
  • Highly absorbable, better absorption.
  • Gentle on the stomach.
  • Supports over 300 processes.
Main Highlights
  • HIGHLY ABSORBABLE: Magnesium glycinate (also known as magnesium bisglycinate) is the most bioavailable form of magnesium. Two glycine molecules are bound to each magnesium molecule through a process called "chelating," leading to increased solubility and better absorption.
  • GENTLE ON STOMACH: Standard magnesium supplements can cause stomach upset and laxative-like effects. The chelation process ensures that more of the magnesium powder is ready for use by the body without digestive disruption.
  • FULL-BODY BENEFITS: Magnesium is one of the best essential minerals for the body. It is involved in over 300 crucial biological processes, including sleep & relaxation, immunity, muscle soreness, metabolism and so much more.*
  • SMALL CAPSULES: Nobi’s small, 2-capsule servings are flavorless and easy to swallow. Each serving yields 400 mg of highly-absorbable magnesium, and each bottle contains 120 capsules.
  • MADE WITH YOU IN MIND: Magnesium Glycinate by Nobi Nutrition is Third-Party Tested and formulated without the top 9 allergens. It is manufactured in a facility that adheres to GMP guidelines.
